Erasers are made from either natural or synthetic rubber. Natural rubber is produced from latex that is collected from rubber trees. Water is removed from the latex, increasing the rubber content to 60%. Acid is added to the liquid concentrate in order to produce solid sheets of dry rubber.
Other erasers are made to temporarily attach to pencils. Some erasers are enclosed in wooden cases that resemble pencils. These erasers, designed to be sharpened like pencils, often have a brush attached. This is used to brush away small pieces of the eraser left behind after it removes a mark.
